A travel advisory for the county will remain in effect until Thursday morning at 5 a.m.

UPDATE AT 7:30 A.M.: Ontario County Sheriff Philip Povero is urging residents to avoid unnecessary travel until Thursday morning at the earliest.

A travel advisory for the county will remain in effect until Thursday morning at 5 a.m.

"Significant amounts of snowfall and wind will continue throughout today and tonight that will make travel dangerous," according to a press release from the Sheriff's Office. "Plow crews may not be on the road overnight (Wednesday/Thursday), so road surfaces could see significant accumulations before they resume plowing tomorrow morning."

All area schools, including in Canandaigua, Geneva, Naples, Manchester-Shortsville and Finger Lakes Community College, remain closed for a second straight day Wednesday because of the weather.

 UPDATED AT 5 P.M.: Heavy snow continues to fall and another 4-to-6 inches is expected to fall Tuesday evening, according to Ontario County Sheriff Philip Povero. Wind is also expected to increase, which may cause visibility issues.

Due to hazardous conditions, Povero and Wayne County Sheriff Barry Virts issued a Travel Advisory within their counties until 10 p.m. Tuesday. Motorists may continue to travel, and as traffic is expected to increase as people leave work and return home, extra caution is urged.

Anyone on the road should beware of hazardous road conditions.

Beginning at 10 p.m. and until 5 a.m. Wednesday, Povero and Virts advise no unnecessary travel on county roads. During this time, snow is expected to be falling and highway crews will be off the highway or operating with reduced forces, to enable crews to get some rest. Motorists who decide to travel then need to be extra cautious, considering changing weather and highway conditions they will encounter.

Ontario County 911 reported 30 highway related mishaps in the county since midnight. This includes 13 reports of cars in a ditch, 2 rollover crashes, 4 crashes with injuries (all minor) and 11 property damage-only crashes. The crashes have taken place in all areas of the county.

Extra sheriff patrols are on duty and will continue to monitor highway conditions and respond to calls for service as needed. Povero reminds motorists to use caution around snowplows and allow plows space to work on roads.

RTS this afternoon announced a change in bus schedules as a result of the storm. The Route 5x Express 4 p.m. trip from Eastview Mall to Geneva was the last run of the day for that service. The 5 p.m. trip from Geneva and the 6 p.m. trip from Eastview Mall have been canceled.

The snow will continue and wind is expected to increase as the day goes on. Blowing snow will cause reduced visibility and may create more difficult driving conditions.

Anyone needing help during the snow event can call 911 for assistance.

All schools in the county, except Red Jacket School (Shortsville-Manchester), closed for the day, and this has reduced traffic in the county. The Red Jacket Schools will be closing at 11 am. Extra sheriff patrols are on duty, and they will continue to monitor highway conditions and respond to calls for service as needed.

The storm forecast is for growing intensity throughout the day with total accumulations of 4-8 inches of snow today and an additional 3-6 inches tonight.

UPDATE AT 6:30 A.M.: The National Weather Service says the dividing line between snow and a wintry mix from a nor'easter pushing through the southern New Jersey-Pennsylvania region has moved farther inland, cutting down the anticipated snow accumulation, but increasing the chance of icing.

NWS Meteorologist Sarah Johnson, in Mount Holly, New Jersey, says the dividing line between snow and a mix of snow, sleet and rain has pushed west, from the Jersey coast into Philadelphia. She says that lowers anticipated snow totals, but increases the threat of icing from sleet and freezing rain along the Interstate 95 corridor.

While the snow totals might be lower, Johnson warns that New Jersey shore areas can still expect strong winds, with gusts between 50 and 55 mph. The I-95 corridor could get wind gusts of up to 40 mph.

OPM also announced early Tuesday that non-emergency federal employees also have the option to take unscheduled leave or to conduct unscheduled telework.

UPDATE AT 2 A.M.: The snow threat in the Northeast is causing college basketball teams to alter their travel plans.

Teams chasing a college basketball title are contending with an unexpected wrinkle that's making last-minute travel plans difficult — a fierce storm bearing down on the Northeast that could dump up to two feet of snow in some places.

"We are closely tracking the weather and working with our travel partners and teams in the tournament to ensure the safety of our student-athletes, coaches, administrators, officials and fans," the NCAA said in a statement.

Villanova, top overall seed in the men's NCAA Tournament, left Philadelphia on Monday afternoon for Buffalo, New York, to get ahead of the storm.

There is less of a chance that the women's tournament would be affected. UConn is the only Northeast team hosting and they play Saturday, giving teams more time to arrive in Connecticut.

U.S. airlines canceled thousands of flights ahead of the storm. Teams in the men's and women's NCAA Tournaments have chartered flights so any backlog on commercial planes shouldn't be a problem.
